cache_page with Class Based Views

Question

I\'m trying to do cache_page with class based views (TemplateView) and i\'m not able to. I followed instructions here:

Django--URL Caching Failing for Class Based Vi

Answer 1

According to the caching docs, the correct way to cache a CBV in the URLs is:

from django.views.decorators.cache import cache_page

url(r'^my_url/?$', cache_page(60*60)(MyView.as_view())),

Note that the answer you linked to is out of date. The old way of using the decorator has been removed (changeset).

Answer 2

I created this little mixin generator to do the caching in the views file, instead of in the URL conf:

def CachedView(cache_time=60 * 60):
    """
    Mixing generator for caching class-based views.

    Example usage:

    class MyView(CachedView(60), TemplateView):
        ....

    :param cache_time: time to cache the page, in seconds
    :return: a mixin for caching a view for a particular number of seconds
    """
    class CacheMixin(object):
        @classmethod
        def as_view(cls, **initkwargs):
            return cache_page(cache_time)(
                super(CacheMixin, cls).as_view(**initkwargs)
            )
    return CacheMixin
